Re: Decibel readings backwards
The other thing is, in recording 0dB is your highest point that you physically can't exceed. It's the point after which the top of the waveform is 'clipped' off, and your signal starts to distort. CD audio can't exceed 0dB at any point.
I think that's perhaps why it goes up to 0, Pocket. You can go infinitely lower than that but no higher.
